Description

A spinning device for compact composite yarn

technical field

The invention relates to a spinning device for compacted composite yarns, which is used for spinning compacted composite yarns and belongs to the field of textiles.

Background technique

Compact spinning, also known as compact spinning, has been significantly developed and applied since its birth at the end of the 20th century. Aiming at the existence of the twisting triangle in ring spinning is an important reason for yarn hairiness and low strength, the technical principle adopted by compact spinning is to reduce the "twisting triangle" of ring spinning, using different methods to make After the roving is drawn, it is "accumulated first, then twisted" to become a concentrated yarn. Compared with ring-spun yarn, compact yarn has the characteristics of less harmful hairiness and higher yarn strength. At present, compact spinning technology has been widely used in the world and is still developing.

Composite yarn refers to the combination of two or more fiber materials with the same or different properties to complement each other to form a new type of yarn that can fully exert its respective functions. The development of composite yarn not only makes up for the defects of single component fibers, but also makes full use of the advantages of different materials and fibers with different properties, and realizes the best combination and application of fibers. With the continuous improvement of people's requirements for textile fabrics, single-material fabrics can no longer meet people's needs for individuality, diversification, and functionality. The development of composite yarns shows the colorful appearance and style of fabrics, and improves The comfort and functionality of the fabric. The different yarn structures and properties of composite yarns increase the scope of application of fabrics, and are generally welcomed by consumers, and their uses will become more extensive.

Nowadays, simple composite spinning or simple compact spinning has been difficult to meet people's needs, and people have also developed new composite spinning methods and devices. For example, the German Suessen company installed compact spinning devices on the basis of siro spinning to form compact spinning siro yarns; Luo Feier yarn, and so on. This new type of yarn not only has many advantages of compact spinning, but also has the advantages of composite spinning. But above-mentioned these two kinds of methods still have limitation, and the most obvious defect is that can't be spun to have the accumulation composite yarn of multiple changing mechanism.

The middle part of the hanging spindle 16 on both sides of the roving creel 1 is provided with a yarn guide rod 17, and the left and right sides of the straight rod middle part of the roving creel 1 are respectively provided with a slowly reciprocating traverse guide bell mouth 18. The bottom end of the straight bar is provided with a frame 19, and the top both sides of the frame 19 are respectively provided with a drafting device 15, and a yarn guide hook 20 is provided near the top on the left side of the frame 19, and a yarn guide hook 20 is arranged below the yarn guide hook 20. There is a bobbin 21, a traveler 22 is provided below the bobbin 21, a feeding device 2 is provided on the spindle 16 of the roving creel 1, and a gathering device 14 is provided at the front end of the drafting device 15.

Wherein, the drafting device 15 is composed of the intermeshing back roller 3 and the first top roller 4 and the intermeshing middle roller 5 and the second top roller 6, wherein the back roller 3 and the first top roller 4 are arranged in parallel in the center Roller 5 and the front end of the second top roller 6.

The feeding device 2 is composed of two roving feeding devices 12 and a filament feeding device 13 arranged side by side on the spindles of the roving creel 1 .

The accumulating device 14 is composed of a front roller 7, a bridge gear 8, an accumulating roller 9, a special-shaped tube 10 and a grid ring 11; wherein, the front roller 7, the bridge gear 8 and the accumulating roller 9 are sequentially meshed into a "human" character type, a special-shaped pipe 10 is engaged under the front roller 7 and the accumulation roller 9, and a grid ring 11 is provided on the periphery of the special-shaped pipe 10.

On the working surface of the special-shaped pipe 10, there are two inclined grooves in the same direction; the inclined angle of the inclined grooves is 8 degrees, the width of the inclined grooves is 1.2mm, and the distance between the two inclined grooves is 10mm.

During spinning, the two rovings pass through the drafting device 15 composed of the rear roller 3, the top roller 4, the middle roller 5 and the top roller 6, and meet with the filaments to enter the front roller 7, the bridge gear 8, the accumulation roller 9, the special-shaped The tube 10 and the grid ring 11 constitute the compacting device 14, and then output the twisted compacted spun composite yarn.

The working principle of the present invention is: two rovings are unwound from the roving feeding device 12 of the roving creel 1 hanging spindle 16, passed through the yarn guide rod 17 and the slowly reciprocating traverse guide bell mouth 18, fed and drafted The device 15 performs the drafting.
